To take a cold backup of an Oracle DB, our system engineer used the following command :
tar cf - /data/oracle/instance1 | compress - > /SAVE/cold_backup_instance1.tar.Z
(All db files are under instance1. About 4.5 Gb).
Anyone could give me a simple way to restaure from : cold_backup_instance1.tar.Z
I tried few commands (uncompress and tar -xf in the same time) but it seems that the system
try to uncompress and then extract files (with tar x) : but the operation ends when the tar
file reachs 2 Go ... (file size limit in our system : HP-UX 10.20 is 2Go)
